The main function of the online UPS under the power supply condition is to stabilize the voltage and prevent electric wave interference; in the event of a power failure, it uses a backup DC power supply (battery pack) to supply power to the inverter. Since the inverter is always working, there is no switching time problem, and it is suitable for occasions with strict requirements on the power supply.
